(Using Virtual Box 4.2.0, Ubuntu 12.10 64bit)
Although the GuestAdditions and 3D acceleration instructions were meant for 4.2.4 and 4.2.6 I wanted to try them for 4.2.0.
Now that I start the VM, I get a black command prompt screen.
As I am new to Linux, I tried to remove the last line from the modules file in /etc/ by typing
sed '$d' < modules
This did remove the vboxvideo line but I'm still getting the black command screen.
How do I get back the standard visual desktop?
The appropriate way to uninstall guest additions from a virtual box guest is to run the script provided:
user@guset:$ sudo ./opt/<VirtualBoxAddtions-x.x.xx>/uninstall.sh
Replace the x placeholders with the ones for your vitualbox version.
Alternatively you can try to install the appropriate version of the guest additions over the existing guest additions. A command line way to do this is outlined here:
However it is strongly recommended to upgrade virtual box to the most recent version to be able to run the latest Ubuntu release without issues.
